LastObject has a small range of products, which generally expands via the occasional product launch on Kickstarter. Their goal is to replace usually-disposable items with washable, reusable equivalents. Thus far I have tried LastTissue, LastPad, and their Detergent Sheets.
The tissues are basically a stack of 18 cotton handkerchiefs packaged in a silicone tissue box. The handkerchiefs are cleverly folded so that you can pull one out of the box and the next one will poke out the top, just like paper tissues. Instructions on the cardboard packaging show you how to re-fold them once they've been washed and it's time to refill the box. There is also a 6-handkerchief portable version.
A traditionalist might look at this and say, "Well, those are just cotton handkerchiefs, which are just how people used to blow their noses before we started manufacturing paper tissues. Why would they need to be in a fancy tissue box?"
You'd be right about that.
The obvious goal here is to appeal to people who don't have that established habit of just tucking a handkerchief into their pocket every morning, or to people who feel the need to always be able to pull a fresh one out of a box instead of carrying around a used one in their pocket. This is for people who still need their "tissues" to use the same form factor as their tissues in a box or little plastic travel pack, even if they are ultimately washable.
The silicone boxes--both the tabletop and pocket models--have a separate compartment where you're supposed to stuff the used ones, with a silicone barrier separating them from the fresh ones. I find this a little icky myself and use a hybrid approach; I just have the tabletop model and put the one I'm using in my pocket for the day. If I'm at home and I'm done with it, it goes straight into the laundry. I don't want the used ones anywhere near the new ones, and I want them washed in the next load, not waiting with snot on them in some container while I possibly forget about them on laundry day.
I also haven't completely phased out my use of paper tissues either; anything grosser than face fluids, or that might stain, gets a paper one. But the cloth handkerchiefs at least cut down on my use of paper ones. They've comfortable and get softer after the first wash, and the clever folding really does work; it's fun to see the technique work so well with cloth.
It's a little tricky to find the page where you can order refills, so here is a convenient link.
LastPad is a washable, reusable replacement for disposable menstrual pads. They're far from the first company to attempt this, but I went ahead and backed the project anyway in hopes they would be more comfortable than other options. I am happy to report that they are thinner and more comfortable than a similar product from Charlie Banana, and do not tend to bunch up very much during use.
That said, anyone with a heavy flow (or even moderate, really) should do their own testing.
They come in three sizes, in pouches that are quite effective at isolating the pad from whatever else you're carrying. The surfaces of the pads themselves are all black (the better to not show stains). You have your choice of colors that applies to the pouches and to a strip of silicone on the back of the pad that keeps it from slipping during use.
As with the tissues, these are meant as a same-form-factor replacement of the associated disposable product. The lack of a truly sticky back may be an issue for some, in which case, a set of full-on period underwear might serve better, and/or a silicone internal solution (try Package Free Shop).
It makes some sense that LastObject would sell these, since their other products all need to be laundered. They still contain the same microplastics as any other detergent sheets, so they are still problematic.
That's especially unfortunate because they are also really effective. In particular, I used them to clean a bike jersey that had gotten splattered with mud and wet-asphalt grit during a rainy ride. By rubbing the sheet right into the stain I was able to get almost all of it out, which was a better success than I'd had previously with that situation.
Like most things that are designed to at least mostly break down, detergent sheets can't be stored forever; they have a shelf life of a couple years. So I can't even just save the box I have and very gradually just use a sheet at a time while traveling; that would take decades.
I will have to see how Blueland detergent does with road stains.
